professional instructions, please see Earlens Light-Driven Hearing Aid Hearing Professional Instructions.
2. Wireless Earlens Light-Driven Hearing Aid Device Description
The wireless Earlens Light-Driven Hearing Aid uses non-visible light
to send sound information to a customized Tympanic Lens (Lens).
The Lens converts the light into vibrations that are directly applied to
the eardrum and are perceived as sound (Figure 1). The Earlens
Hearing Aid System includes the following:
Lens
Photon™ 2 Processor
Light Tip
Earlens Fitting Software (ELF)
Charger with Power Adapter
Earlens Impression System
Mineral Oil
Earlens Control Mobile Application
2.1. Tympanic Lens
The Lens (Figure 2) is designed to receive light signals from the
Light Tip and convert the light signals into mechanical vibrations
of the tympanic membrane (TM). The Lens is customized for
each patient and is placed in to position by a trained physician. It
is placed at the end of the ear canal on the skin around the TM.
2.2. Photon™2 Processor and Light Tip
The Processor is directly connected to the Light Tip via the cable
(Figure 3). The Processor is designed to pick-up sounds via the
microphones, apply signal processing and transmit the signal via
the cable to the Light Tip. The Processor should be placed in the
Charger for recharging every day.
The Processor features a wireless antenna that allows for direct
connectivity with select smartphones and tablets. The use of this
feature is optional. Information on settings and use of the
wireless functionality can be found in the hearing professional
and patient Instructions for Use. For additional information,
please contact your Earlens support team or visit
www.earlens.com/connectivity.
The Light Tip is connected to the Processor via the cable and
can be physically modified by a hearing professional to improve
fit. The Light Tip shell features a large opening or vent, which is
designed to allow the ear canal to have an open, non-occluding
feel (Figure 4). The Light Tip is specifically designed to stabilize
and aim the emitter at the Lens.

2.3. Earlens Fitting Software (ELF)
ELF is used to program the Processor, enabling the hearing professional to calibrate and program the
Processor specific to the patient’s needs.
2.4. Earlens Charger and Power Adaptor
The Charger is designed to recharge the Processors
(Figure 5). When connected to the wall power
adaptor, the Charger houses and chargers either
one or two Processors simultaneously. An AC wall
power adaptor is included.
2.5. Earlens Impression System
The Earlens Impression System is used by the
physician to collect a deep ear canal impression. The
impression is used to manufacture the customized
Lens and Light Tip.
2.6. Mineral Oil
White mineral oil (food grade) is used to lubricate the
eardrum to keep the Lens in place and functioning
properly. To maintain the devices, it is recommended
that patients apply two pumps of mineral oil to their ears daily.
3. Indications for Use
The wireless Earlens Light Driven Hearing Aid (a.k.a. Earlens Hearing Aid) transmits amplified sound by
vibrating the eardrum through direct contact. It is indicated for
individuals 18 years and older with a mild to severe sensorineural
hearing impairment who can benefit from amplification. The device
can provide the full spectrum of amplification that includes 125 Hz
10,000 Hz.
4. Fitting Range
The Earlens Light Driven Hearing Aid provides the full spectrum of
amplification that includes 125 Hz 10,000 Hz. The audiometric
fitting range for the Earlens Hearing Aid is shown in Figure 6.
5. Contraindications
The patient must not have any known or active medical issues that
would preclude having a hearing device, including:
a. an abnormal TM (deemed perforated, inflamed or has dimeric or
monomeric area, or in any other way abnormal);
b. an abnormal middle ear or a history of prior middle ear surgery other than tympanostomy tubes;
c. an ear canal anatomy that prevents the physician from seeing an adequate amount of the TM;
d. an anatomical configuration of the external auditory canal that
prevents satisfactory placement of the Lens;
e. a history of chronic and recurrent ear infections in the past 24 months;
f. a rapidly progressive or fluctuating hearing impairment;
g. diagnosed with having a compromised immune system which may impact the tissue of the auricle
or ear canal, such as keratosis obturans, ichthyosis, eczema of the auricle or ear canal, or
received radiation of the head ever or chemotherapy for cancer within the last six years.
Note: Once the otologic and audiologic indications for use were met, approximately 95% of patients were
successfully fit with the Earlens Hearing Aid (5% were unable to anatomically accommodate the Lens).

6. Warnings
Before using the Earlens Hearing Aid, make sure you read and understand each of the following
safety warnings:
The Earlens Hearing Aid is considered MR unsafe. The Lens should be removed prior to an MRI
exam or MRI exposure. Only physicians trained in Ear, Nose & Throat procedures should
place or remove the Lens.
The patient should not use therapeutic or medical diathermy using electromagnetic radiation
(magnetic induction coils or microwave) from the shoulders up with Earlens Hearing Aid in place.
The Processor and Light Tip unit contain a Class 1 laser product. It is safe to
use under normal operating conditions. The Class 1 laser light is NOT visible.
Do NOT look directly into the laser or aim directly into the eyes. Should any part
of the Earlens Hearing Aid become damaged, the patient should discontinue
use and contact their hearing professional.
If the patient experiences discomfort or pain in their ear, they should contact their ENT physician
immediately. Only physicians trained in Ear, Nose & Throat procedures should place or remove
the Lens.
The patient should not insert foreign objects into the ear, such as Q-tips, bobby pins or
fingernails. Insertion of foreign objects could result in pain and damage to the ear, damage to the
Lens or cause it to operate improperly.
The patient should contact their hearing professional if they experience discharge from the ear or
persistent discomfort or any other problems.
Should the Processor become unusually warm or hot, the patient should promptly remove it,
discontinue use and contact their hearing professional.
Do not crush, short circuit, modify or disassemble any component of the Earlens Hearing Aid.
Keep all components of the Earlens Hearing Aid out of the reach of children, pets and others, to
avoid risk of swallowing.
Do not incinerate any component of the Earlens Hearing Aid or use near open flame. Handle
waste from electronic equipment per local regulations.
7. Precautions
Before using the Earlens Hearing Aid, make sure you and the patient read and understand each
of the following safety precautions.
Individuals with known nickel sensitivity/allergy should be informed that the Lens component
contains nickel that is coated with a parylene barrier. If an allergic reaction develops, the Lens
should be promptly removed.
The Lens was tested for nickel leaching and found to be compliant and within the safe levels
identified in European standard EN1811. Traces of oxidation (discoloration) may be visible on the
Lens surface following prolonged wear. Testing indicated the oxidation was not likely to affect the
structural integrity of the Lens within the 1 year expected life.
Only hearing healthcare professionals trained in the fitting of hearing aids may fit the Earlens
Processor and Light Tip.
The Earlens Hearing Aid is custom designed and intended to be used for a single patient.
The Light Tip is designed to sit a set distance from the Lens. Sound output may deviate if the
Light Tip is not inserted to the proper depth. If the sound output does deviate, the patient can
reposition the Light Tip until optimal sound output is achieved.
Earplugs or headphones can be used with the Lens in place as long as care is taken not to over-
insert them and they do not protrude deeply into the ear canal.
The patient may shower, bathe or swim with the Lens in place. Ear plugs may be used to prevent
water from entering the ears so long as care is taken to not over-insert them. Removing water
from ears may be more difficult with the Lens in place.

12/19/19
If the patient has small or unusually shaped ear canals, they may be at greater risk for ear canal
abrasions, either from the ear impression procedure or from Light Tip use.
The patient should avoid getting the Processor wet, as it may damage the device. The patient
must remove the Processor prior to showering, swimming, or bathing.
The patient may experience a reduction in their hearing levels when the Lens is in place but the
Processor is not activated.
Do not direct streams of liquid (i.e. isopropyl alcohol, hydrogen peroxide, DeBrox) into ears, as
this may cause the Lens to become dislodged or cause damage to the device.
Failure to oil the ear canal may result in Lens displacement.
Do not place any component of the Earlens Hearing Aid into a microwave, or near a significant
source of static electricity.
Use only the Earlens Charger and AC wall adapter provided. Although other adapters may look
similar, they may cause damage to the Earlens Hearing Aid.
Handle the components carefully and prevent hard knocks. Do not drop them as it may damage
the Earlens Hearing Aid.
If the Earlens Processor fails to operate or if it appears damaged, including the presence of
battery leakage or swelling, the patient should promptly remove the Processor, discontinue use
and contact their hearing professional.
Only clean the Processor with a soft cloth. Do not use chemicals (i.e. hairspray) in close proximity
or to clean the Processor.
Keep Charger cord out of reach of individuals who may be at risk of strangulation.
Electromagnetic fields produced by other electrical equipment such as cell phones, metal
detectors, microwaves, RFID systems and commercial theft detection systems (also known as
electronic article surveillance [EAS]) may interfere with the Earlens Hearing Aid. In the event that
the patient perceives unexpected noise or interference in the presence of the Earlens Hearing
Aids, move away from the source to mitigate the potential interference. If the patient has further
concerns they should remove the Processors and contact their hearing professional.
8. Clinical Study Results
The Definitive Clinical Study of the Earlens Light Driven Hearing Aid confirmed the safety and
effectiveness of the Earlens Hearing Aid for individuals with a mild to severe sensorineural hearing
impairment between the frequencies of 125 Hz10,000 Hz. The prospective, single arm study assessed
48 subjects (96 ears) who wore the fully activated Earlens Hearing Aid in both ears in their daily lives for
four months per study protocol. Safety and effectiveness were assessed during the four months.
8.1. Study Demographics
The average age of the study population was 69 years with a gender ratio of 60% for males and 40% for
females. The subjects were seen across three clinical sites with the largest enrollment at Site 1 (Site 1=
21, Site 2=15 and Site 3=12). All participants were experienced hearing aid users.
8.2. Safety Outcomes
The primary safety endpoint was intended to demonstrate that use of the Earlens Hearing Aid did not
result in a change in residual hearing function. The objective was to identify any change in baseline
hearing after four months of device usage using a four frequency threshold criteria (500, 1000, 2000, and
4000 Hz, referred to as PTA4). A determination of clinically non-significant hearing threshold change was
made if calculated PTA4 hearing change of the subject population was less than 10 dB. After wearing the
Lens for 4 months, no decrease in hearing sensitivity of more than 10 dB was observed. A secondary
safety endpoint assessed any decrease in hearing sensitivity of >10 dB by subject per ear at each test
frequency. After four months of use no subjects exhibited a decrease of >10 dB for either ear at any
frequency. In addition, no serious device or procedure-related adverse events were reported during the
trial. There were 31 adverse events reported in 20 subjects for 22 ears. All but one of the adverse events
were temporary and resolved. One subject report of a ‘fullness’ sensation when wearing the Aid did not
change during the trial and effectiveness outcomes were not impacted. The subject continued use

throughout the study period of four months. Table 1 presents the adverse events by type, frequency of
occurrence and resolution status at the conclusion of the study.
8.3. Effectiveness Outcomes
The primary efficacy endpoint was intended to demonstrate device effectiveness by improving speech
recognition using the Northwestern Auditory Test No.6 (NU-6) test of word recognition with the Earlens
Hearing Aid at a speech level of 45 dB HL. The objective was to show that the Earlens Hearing Aid
provides a statistically significant improvement in mean aided word recognition at 30 days post placement
when compared to the baseline unaided condition measured prior to placement. The average baseline
unaided score was 52% and the average aided score was 85% (Figure 7); this improvement was
statistically significant (p<0.0001). A secondary measure of device effectiveness was defined as more
than 10 dB improvement (functional gain) in thresholds over the range of frequencies from 2,000 to
10,000 Hz for aided measured at 30 days post placement when compared to unaided measured prior to
placement. Mean functional gain was 30.5 dB (p<0.0001), indicating that the Earlens Hearing Aid was
able to deliver significant functional gain (Figure 8). Functional gain reached a maximum of 68 dB at 9-10
kHz.
An additional measure of device effectiveness was perceived benefit as measured by the Abbreviated
Profile of Hearing Aid Benefit (APHAB). The average baseline unaided percentage of communication
difficulties was 58% (standard deviation = 16%), the percentage of difficulties decreased to 30%
(standard deviation = 13%) with the subject’s own air conduction hearing aid, and for Earlens it was 29%

(standard deviation = 14%). 92% of subjects completing the study (35 out of 38) perceived a clinically
significant improvement for Earlens relative to unaided as measured by APHAB.
8.4. Temporary TM Damping
The Lens is designed to remain in place even when the Processor is not worn. When the Processor is
removed (swimming, bathing, sleeping), users may experience TM damping, which would be interpreted
as slight reduction of sound, due to the loading effect of the Lens. The effect on PTA (500 Hz, 1000 Hz
and 2000 Hz) averaged 4 dB, which is immediately reversed when the Lens is removed. When the
Processor is in place, the gain delivered by the Earlens Hearing Aid more than overcomes the TM
damping effect.
8.5. Summary of Extended Study
The safety and effectiveness of the Earlens Hearing Aid was monitored beyond the 4 months of the
Definitive Study. In the Extended Study, 24 subjects (48 ears) opted to continue wearing the Earlens
Hearing Aid after completing the Definitive study. At the conclusion of the Extended Study, 33 ears had at
least 12 months of cumulative Lens wear with no change in unaided air conduction hearing thresholds
under earphones. Of the 24 active subjects in the Extended Wear Study, 11 related AEs were
experienced by 8 subjects in 10 ears. All events were temporary and resolved. Nine of 11 AEs were
related to ear cleaning pre-impression (3 AEs), the impression procedure (4 AEs), or the inspection
process pre-impression (2 AE). Two of the related AEs were attributed to Light Tip fit and both were
resolved after Light Tip modification. One subject continues to report a sensation of fullness.
Driven on the results of the Definitive study, the Earlens Hearing Aid has been shown to be safe and
effective in delivering the full spectrum of amplification from 125 to 10,000Hz.
9. Operating Instructions
9.1. Ear Canal Impression
Before making the ear canal impression using the Earlens Impression System, please read and follow the
precautions and procedures found in the Earlens Impression System Instructions for Use.
9.2. Lens Placement
a. Visually inspect the Lens packaging. DO NOT use if there is any visible damage.
b. Explain to the patient that the ear will be inspected and cleaned, then lubricated with oil (which
may cause some sensations of stuffiness), and the device will be inserted. Instruct the patient to
remain still during the procedure.
c. With the patient in the supine position, use a binocular microscope to inspect the external
auditory canal and the tympanic membrane and determine if there are any contraindications for
Lens placement.
d. Remove all cerumen and epithelial debris from the ear canal, anterior sulcus and tympanic
membrane using the usual office instrumentation and small cotton swabs with mineral oil. If there
is any bleeding or development of contraindications as a result of cleaning of the ear canal, do
not place Lens.
e. Lubricate the ear canal and TM with mineral oil.
f. Read the package label to confirm that the device is for the correct patient and ear (left or right).
On the shipping mold, a right Lens is identified by a red dot and a left by a blue dot.
IFU00021vP

12/19/19
g. The Lens also includes an indicator for a right or left device
which, is dependent on the Lens design. There are two
possible designs you may encounter:
o Grasping Tab left/right of Photodetector (Figure
9): When facing the Photodetector, the Grasping
Tab for a right Lens is located on the right side and
the Grasping Tab for the left Lens is located on the
left side.
o Grasping Tab centered below Photodetector
(Figure 10): When facing the Photodetector, the
Grasping Tab is located below and centered. A right
Lens will have a red dot located on the right side
and a left Lens will have a blue dot located on the
left side.
h. Grasp the Lens at the Grasping Tab (Figure 2) using smooth
alligator forceps.
i. Using alligator forceps, gently advance the Lens through a
thin bladed nasal speculum to the medial region of the ear
canal.
j. Then, using an aural speculum and curved pick, gently
advance the Lens onto the TM and position it such that the
Perimeter Platform is congruent with the anatomical contours of the patient’s anatomical
counterparts. At this point the Umbo platform will be in direct contact with the TM.
k. Once satisfactory positioning is achieved, remove the speculum.
9.3. Lens Removal
a. Explain to the patient that the ear will be inspected and cleaned, lubricated with mineral oil (which
may cause some sensations of stuffiness), and the device will be gently removed. Instruct the
patient to remain still during the procedure.
b. With the patient in the supine position use a binocular microscope to inspect the external auditory
canal and the TM, and determine the position of the device and the location of the grasping tab.
c. Lubricate the ear canal with mineral oil.
d. Using a right angle hook, use the Grasping Tab to capture the device to be removed and slowly
deliver it into the lateral canal. Withdraw the speculum, and use the curved pick to remove the
Lens.
e. Inspect the external auditory canal and the TM.
9.4. Cleaning and Preparing the Lens for Reinsertion
If a Lens is removed the device and canal must be cleaned prior to reinsertion of the device.
a. Remove the Lens per the Lens Removal instructions and carefully place the device in a dish of
mineral oil for soaking.
b. Thoroughly clean the ear canal, anterior sulcus and TM using cotton swabs, mineral oil and
suction as needed. Remove any debris, including epithelial tissue that may have built up in the
anterior sulcus or on the TM.
I. Hydrogen peroxide solution can be used to loosen hard epithelium or cerumen adhered
to the TM or anterior sulcus. Before placement of the Lens ensure all of the hydrogen
peroxide is completely suctioned out, and the applied area is cleaned with mineral oil, to
avoid device contact with the hydrogen peroxide solution.
c. Inspect the umbo of the TM and the area where the Perimeter Platform of the Lens was resting to
ensure it is free of debris or epithelial tissue.
d. After soaking, grasp the Lens at the Grasping Tab using alligator forceps under visual
magnification. Carefully suction any debris remaining from the Perimeter Platform and/or
Photodetector.

I. Avoid directly contacting the support springs and Umbo Platform while cleaning the Lens.
II. Holding the Grasping Tab of the Lens with the alligator forceps prevents the Lens from
being suctioned up, dropped to the floor or experiencing undue pressure on the Umbo
Platform. It also aids to control the suction to the Lens.
e. Following the cleaning carefully inspect the Lens to ensure it is free of debris and is not damaged.
I. Replacing a Lens that is not free of debris or is damaged may cause the device to
displace.
f. Proceed with device placement per the instructions outlined in Section 9.2.
9.5. Troubleshooting
The expected life for the Lens is one year. The Lens is expected to exhibit the same failure modes
regardless of the duration of wear. The Lens can become displaced from the tympanic membrane,
blocked by debris or degrade over time. This may cause the sound output of the Earlens Hearing Aid to
cease, become reduced or become intermittent. Perform the following troubleshooting steps to assess
Lens function:
a. Inspect the ear canal and Lens. If the Lens is blocked by debris, carefully clean the ear canal. If
removal or reinsertion is required, follow Lens Removal and Cleaning and Preparing Lens for
Reinsertion instructions above.
b. Inspect the position of the Lens on ear. If the perimeter platform does not appear to be in contact
with the wall of the ear canal, the Lens may be displaced.
I. In the event of displacement of the Lens, remove the device per Lens Removal instructions
and replace following the Cleaning and Preparing Lens for Reinsertion operating
instructions.
c. Inspect the appearance of the Lens on ear. If the Lens appears damaged or abnormal, remove
using the Lens Removal instructions and contact Earlens.
d. If there is a suspected performance issue with the Lens that otherwise appears fine visually (e.g.
significant elevation of system Light Calibration), remove the device per Lens Removal
instructions and replace following the Cleaning and Preparing Lens for Reinsertion operating
instructions. Once Lens is replaced assess if the suspected performance issue is resolved (e.g.
system Light Calibration is no longer elevated).
If after performing the troubleshooting steps listed above, the Lens still does not function, remove it using
the Lens Removal operating instructions and contact Earlens.
9.6. Care & Maintenance
a. Store the Earlens Hearing Aid in a clean, dry location out of direct sunlight.
b. The expected life of the Lens is one year. As for any patient with a hearing assist device, it is
recommended that the patient return annually to their hearing professional(s) to monitor their
audiologic and otologic status.
